... of natural convection. The objective here is to develop a computationally efficient model capable of capturing the physics of the flow and heat transport to predict air renewal rates in the vertical annulus. The small quantities of air infiltrating/exfiltrating through the porous cylinder over its upstream...

...Mahfoud Djezzar; Michel Daguenet The authors express the Boussinesq equations of the laminar thermal and natural convection, in the case of permanent and bidimensional flow, in an annular space between two confocal elliptic cylinders. The latter is oriented at an arbitrary angle α with respect...

... predictions and the numerical results obtained by solving the full governing equations. For large Rayleigh numbers ( R T ⪢ 1 ), an approximate solution valid in the limit of the boundary layer regime is obtained. 30 09 2004 12 05 2005 natural convection two-phase flow fluid dynamics flow...

... permeability, where natural convection can occur. The thermo solutal convection with heterogeneous permeability was studied in terms of flow pattern, concentration distribution, component separation ratio, and Soret coefficient distribution. A consistent analysis was conducted and it is concluded...

...Antonio Campo; Oronzio Manca; Biagio Morrone Laminar natural convection of metallic fluids ( Pr ⪡ 1 ) between vertical parallel plate channels with isoflux heating is investigated numerically in this work. The full elliptic Navier-Stokes and energy equations have been solved with the combination...
